AU Delegation to Meet With Libyan Rebels VOA News April 11, 2011 A delegation of African leaders is heading to the Libyan rebel-stronghold of Benghazi Monday to present a plan for a cease-fire they say has already been accepted by Libyan leader Moammar Gadhafi. African Union officials say the proposal calls for an immediate cease-fire, talks between the rebels and the government, the protection of foreign nationals in Libya and the extension of humanitarian assistance to civilians. Rebel leaders said Monday they will consider the proposal, but are insisting that Gadhafi step down. Libyan officials have said that is not an option. South African President Jacob Zuma and three other African heads of state met with Gadhafi for several hours at his compound in Tripoli on Sunday. The South African leader also called on NATO to stop airstrikes on government targets to "give a cease-fire a chance." Meanwhile, NATO airstrikes have pushed loyalist forces out of the strategic eastern city of Ajdabiya, reportedly allowing rebels to reestablish control there. NATO says its airstrikes Sunday destroyed 11 government tanks near Ajdabiya and 14 near the western rebel-held city of Misrata. Lieutenant General Charles Bouchard says the strikes were needed because pro-Gadhafi forces were brutally shelling Libyans. Medics and reporters say the fighting at Ajdabiya has killed at least 12 people during the past few days. Zuma was joined by the presidents of Mauritania, Mali and Congo on his mediation mission as well as a representative from Uganda. Some information for this report was provided by AFP and Reuters. .
